The ancient Egyptians have long conceived their nation as two lands held in balance, one upper, or upstream, and one lower, encompassing the Delta down to the coast. Tradition tells us that their two lands was divided by a boundary line plotted at the Old Kingdom capital of Memphis. Beyond the mythological cosmology of the union of the lands, is the metaphysical concepts and esoteric science of mysticism and duality, which Egypt, itself has been founded upon.
